METAL WINDOW FRAME AND SASHES.

Application filed May 12, 1922, Serial No. 560,288. Renewed September 2,1925.

To all whom it may (072/07)? Be it known that I, HARRY E. CAMPBELL, acitizen of the United States, residing at New York, in the county of NewYork and State of New York, have invented a certain new and usefulImprovement in Metal Winiow Frames and Sashes, of which the following isa specification.

The invention relates more particularly to metal window-frames andsashes sliding therein, and consists in the mechanism, hereinafter setforth, whereby certain joints between the sashes and the frame areclosed, the sashes are prevented from rattling in the frame, and alsomay be clamped in closed position so that they cannot be opened untilthe clamping pressure is released. The device is here shown applied towindows of the type set forth in I. S. Letters Patent Nos. 1,222,357 and1,222,358 granted to me April 10, 1917, in which the vertically slidingupper and lower sashes are provided with laterally extending metalplates which cuter and travel in gaps formed in the inner walls of thejambs.

In my pending application Serial No. 547,- 429, filed March 28, 1922,for a metal window-frame and sashes, I have described and claimed thespecific construction of frame and sashes to which my present inventionis here shown applied, to which application reference is made for a moredetailed description of said construction.

The accompanying drawings are horizontal sections through one jaml) andportions of the sashes cooperating therewith, said sections beingsimilar to those shown n Figs. 5 and 6 of in application Serial No.547,429 aforesaid. n Fig. 1 the joint at Q, between the lower sash andthe inner wall of thejamb is shown open, and in Fig. 2 said joint isshown closed.

Similar letters and numbers of reference indicate like parts.

The jambs of the window-frame, one of which is shown at A, are dividedinternally into two compartments into one of which Bthe sash extensionplates, hereinafter described, enter, while the other-C-receives thecounterweights (not shown) for the sashes. The inner wall of jamb A ismade in three sections 10, 11, 12 separated by vertical gaps H I whichextend from top to bottom of said well. The meeting edges of section 10and of the rear jamb wall F are hooked together. The middle section 11of the inner wall is supported on a barrier member J by means of screwbolts, one of which is shown at 24, which bolts pass through elongatedslots in said section. On the member J are flanges 25 and 26 which bearagainst a Wall 19 within the jamb. Flange 25 is bent over, as shown at27.

K is the upper and L the lower sash. On the side rail of sash K in anextension plate M, and on the side rail of sash L is a similar extensionplate N. These plates travel respectively in the gaps H and I as thesashes are raised or lowered.

In order to stop drafts of air from entering the room or building inwhich the window is installed at the joints 0, P between the middlesection 11 of the inner jamb wall and the extensionplates, I havedescribed means whereby both plates M, N are simultaneously forced intocontact with the edges of the middle section 11 by the closing movementof the lower sash upon its seat. Said means comprises an incllnedprojection 34 on flange 26 cooperating with an inclined projection 35 onplate N of the lower sash, so that as said sash is brought to its seatthe pro ection 35 rides over projection 34, so moving the sash plate Nuntil it tightly closes the joint P. At the'same time, the pro ection 34is moved by the same means to cause the barrier member J to slide onwall 19, this movement being permitted b the slot and bolt connectionsof said mem er J with section 11, as shown at 24. By reason of thismovement, the turned over end 27 of flange 25 acting upon extensionplate M of the upper sash forces said extension late M into contact withsection 11, and so 0 oses the joint at 0. Both joints and P are thusclosed simultaneously with and by reason of the closing movement of thelower sash to its seat, the position of the parts being then as shown inFig. 1.

All of the foregoing construction is disclosed and claimed in myaforesaid applicasashes are now brou ht closedly against the edges ofthe middle section, it becomes possible for these parts to move unitedlyin l'lld out and so be liable to rattle in the frame when acted on by astrong wind. I prevent this by the following construction.

On flange 26 of barrier member is a bracket R which carries aninternally threaded sleeve S, through which passes the threaded shaft T.Said shaft extends rearwardly, preferably through the hooked jointbetween the inner wall section 10 and the rear wall F. On the shaft Toutside of wall F is a loose collar U which bears on said wall and maybe held in place by a milled head V, by which the shaft T may tated bythe operator. By suitably rotating shaft T the barrier member J may bemoved in the direction of the arrow a, Fig. 2, and with it, as beforestated, unitedly, the middle section 11 and the extension plate M, so asto cause the extension plate N of the lower sash to close the joint withinner jamb wall section 10 at Q. The closure of this joint may be onlysufficient to prevent the rattling of the sashes, or the shaft T may berotated with sufficient force to cause astrong clamp,- ing of the plateN between wall sections 10 and 11, so that the sashes cannot be openeduntil the )ressui-e is released. As the shaft T cannot e turned from theexterior of the building, it will be evident that my device provides notmerely a means of stopping rattling of the sashes, but an effectivefrictional lock which renders unnecessary any other means for preventingsaid sashes be ing opened for unauthorized entry from the outside.

I claim:

1. A metal window frame'and sash construction, comprising jambs eachhaving an inner wall made in three sections with vertical gaps betweensaid sections, upper and lowersashes, plates laterally extending from bero-.

the side rails of said sashes and entering said gaps, mountings for themiddle sections adapted to permit said middle sections to move inrelation to the other two sections, means within the jamb for movingboth of said sashes and said middle sections in relation to the othertwo sections and mechanism extending out of the jamb for manual'lyoperating said means.

A metal window frame and sash construction comprising jambs having slotsin their inner walls and enlarged openings l ehind such slots, sasheshaving plates adapted to enter said slots and adjustable means withinsaid jambs for changing the clearance between said plates and theportion of the jamb wall that lies between said slots without changingthe position of any other portion of the jamb wall.

3. A window franv. and sash construction comprising jambs, each havingtwo vertical openings in its inner wall, dividing such inner wall intotwo side sections and a middle section, and sashes adapted to slide insaid openings and adjustable means within the jamlzs tor holding thesashes in rel t'ivcly close contact with the middle section of eachjainb wall. such means being operable withoutmoving either of the sidesections of the jamb wall.

4. A metal window-frame and sashes, comprising jambs, each having aninner wall made in three sections with vertical gaps between saidsections, upper and lower sashes, plate laterally extending from siderails of said sashes and entering said gaps, movable supports for saidmiddle sections within said jambs, threaded sleeves on said supports,and rotatable shafts engaging said sleeves and extending through therear walls of said jambs.

In testimony whereof I have atlixcd my signature.

HARRY E. CAMPBELL.
